Pilot operated check,
pilot to open
Common cavity, Size 08
When pressure at 2 rises above the spring bias pressure, the poppet
is pushed from its seat and flow is allowed from 2 to 3. The valve is
normally closed (checked) from 3 to 2. When sufficient pilot pressure
is present at port 1, the pilot piston acts to push the poppet from
its seat and flow is allowed from 3 to 2. Precision machining and
hardening processes allow virtually leak-free performance in the
checked condition.
